The Philadelphia Eagles are going to have a spirited battle to see who wins the quarterback battle during training camp.

If it was left up to running back LeSean McCoy, picking the starting quarterback is an easy choice.

"I think Michael Vick is the starting quarterback," McCoy said in an interview with NJ.com. "People forget -- this is Michael Vick. He's got a lot to prove this year, but he's ready to roll. He knows people are questioning if he can get it done, and he's gonna prove this year he can."

The Eagles re-signed Vick to a one-year contract for around $10 million this offseason. In 2012, Vick struggled, passing for 2,362 yards with 12 touchdowns and 10 interceptions in 10 games last season.

Eagles head coach Chip Kelly has not said whether Vick or Nick Foles, who went 1-5 as the starter last season, will work with the first-team offense when training camp opens.
